United regularly use the train to travel to and from southern away games, something which seemed to take the man by surprise.

Jose Mourinho's men made it back-to-back Premier League wins at Vicarage Road, following on from their success at Burnley prior to the international break.

Nemanja Matic saw red for United in stoppage time and David De Gea was forced into a superb save to seal the points for his side.

The result ended Watford's 100 per cent start to the season while United sit eighth having won three and lost two of their opening five games.
